Export phishing detector result type

[Mrtenz]

Explanation

PhishingDetectorResult expects a PhishingDetectorResultType enum as type property, but the enum was previously not exported. Since it's an enum, we can't access it by using PhishingDetectorResult['type'] either.

We need access to this to mock the result of the phishing controller in tests in the Snaps repo.
